| Résumé: | Purpose. The measurements of the resistance of grounding devices for various purposes using a three-electrode installation under real conditions are considered. Methodology. On the basis of the use of a three-electrode installation, a technique for full-scale measurements of the resistance of a grounding device of any design in an arbitrary soil structure is presented. Results. Based on the measurement results, a system of sixth-order equations is solved which allows to determine the own and mutual resistances in a three-electrode installation with a sufficiently high accuracy. Originality. It is not necessary to find a point of zero potential. Practical value. The proposed technique allows to perform measurements in conditions of dense urban and industrial development. |
